The disclosure includes a method and apparatus for protecting an air vent pipe. In one or more embodiments, a cover can include a plurality of sidewalls and a pipe portal disclosed through at lease on of the side walls. The distal end of an air vent pipe can be disposed through the pipe portal and into the internal volume of the cover. A clamp can secure the cover to the air vent pipe. An access door disposed in a side wall can give access to the clamp and distal end of the air vent pipe and closing and locking the access door with a locking mechanism can prevent unauthorized users from accessing the distal end of the air vent pipe.

The present invention provides a container opening/closing device for opening and closing a lid of a container. The container comprises a container body including an opening and the lid detachably attached to the opening. The device comprises an opening/closing mechanism including a holding portion for holding the lid and a pressing mechanism. The opening/closing mechanism opens and closes the opening by moving the holding portion between a closing position and an open position. The pressing mechanism presses a peripheral edge of the holding portion toward the container body when the opening/closing mechanism moves the lid from the open position to the closing position.

A retrofit latch adapter is configured to replace a pre-existing roller head latch assembly of a pre-existing exit device. The retrofit latch adapter may include a flat latch head that may provide additional security for a door compared with the pre-existing roller head pre-existing latch assembly. A method of installing such a retrofit latch adapter in a preexisting exist device may include rotationally releasing a pre-existing latch assembly having a roller latch head from the pre-existing exit device; rotating the pre-existing latch assembly to linearly decouple the pre-existing latch assembly from a transmission of the pre-existing exit device; removing the pre-existing latch assembly from the pre-existing exit device; rotating the retrofit latch adapter to linearly couple the retrofit latch adapter to the transmission of the pre-existing exit device; inserting the retrofit latch adapter at least partially into a housing of the pre-existing exit device; aligning the flat latch head with an uppermost portion of the housing of the pre-existing exit device; and rotationally securing the retrofit latch adapter to the pre-existing exit device.

A conventional safe proper becomes useless when unable to be locked or unlocked, thereby causing a waste of resources. Locks capable of being locked/unlocked are provided to unfasten a common fastening member, so as to open a door or lid from the body, allow each lock to be freely mounted on and dismounted from a lock mounting portion, and dispose a false lock on each lock. An operating means of locking/unlocking any one of the locks is provided to enable persistent use of a common latch disposed at an identity opening of a safe proper.

A run-up type swing-out door retainer structure includes in a door retainer for a vehicle, a body retainer mounted at a body of the vehicle; and a door retainer mounted at a door of the vehicle to abut the body retainer. A depression formed at the end portion of the body retainer and a protrusion formed at the end portion of the door retainer are divided into an inclined section and a round section to abut each other.

A quick connection and/or fastening system suited to mutually connect and disconnect a first and a second element is disclosed, the system including a first and a second component that are suited to be rigidly fixed to the first and second elements, respectively, the first component and the second component being also suited to be mutually connected and disconnected, the second component being suited to house an end portion of the first component in such a way as to allow its translation inside the second component, the second component comprising also counteracting elements suited to counteract the translation of the end portion of the first component towards the outside of the second component.

Two part sleeves that fasten about existing arms of U-shaped gate latches, and bonded or slide on sleeve and cover devices, and replacement gate latches and methods for preventing injury with oar, fork and U-shaped gate latches that are pivotally attached to fixed support post next to an opening in a fence. The sleeves and covers and replacement oar, fork and U-shaped gate latches have enlarged blunt tips that can include bulbous, dome and ball shapes that prevent injury from children or adults that come into contact with the gate latches.

A door prop includes a rectangular wedge secured horizontally by a first elastic cord in a horizontal position adjacent the door frame upon a door when the door is open. A second elastic cord enables a user to move the wedge away from propping the door when the door is desired to be closed.

A quick connection and/or fastening system suited to mutually connect and disconnect a first and a second element is disclosed, the system including a first and a second component that are suited to be rigidly fixed to the first and second elements, respectively, the first component and the second component being also suited to be mutually connected and disconnected, the second component being suited to house an end portion of the first component in such a way as to allow its translation inside the second component, the second component comprising also counteracting elements suited to counteract the translation of the end portion of the first component towards the outside of the second component.

The invention discloses a locking device and a refrigerator, wherein the locking device comprises a first lock block and a second lock block; the first lock block comprises a base and a tongue; the second lock block comprises an accommodating cavity, a clamping block, a return spring and a pushing block; the pushing block pushes the clamping block to slide in the sliding groove; and the tongue enters the tongue channel to be engaged with the clamping block so that the two lock blocks are engaged with each other. The locking device has the function of automatically adjusting the height difference between different cabinet doors and cabinet bodies, and is therefore more flexibly suitable for locking various cabinets or refrigerators.
